Can mashed potatoes be made a day or two ahead of time and then re-heated? If so, is there anything I should keep in mind? The recipe I'm using has sour cream and roasted onions in it, with potatoes that will be cooked in a rich stock. Thank you. ;o)

Last year, I prepared Pioneer Woman's mashed potatoes (sans Lawry's, though) the day before Thanksgiving, and served 'em up the next day. They are truly over the top delicious and they heat up beautifully. Definitely making them again this year.

I have read that you can make ahead, but you need to stir from time to time while reheating. I don't like the idea of it, but the mashed are such a pain. I wouldn't put that amount of butter and cream cheese in mashed potatoes as the PW recipe has for my family.

Clearly Pioneer Woman's Mashed Potatoes go well for reheating because of the ridiculous amount of fat in them. If you make your original recipe, make sure to use loads of butter along with the sour cream, and use whole fat sour cream as well. If they are too watery, they will surely dry out in the oven/microwave when reheating or create a starchy coating on the top.
